The JBX03531 50m 40GBASE-SR4 QSFP+ Active Optical Cable represents the ideal solution for organizations seeking reliable, cost-effective connectivity in modern data center and enterprise network architectures. As a direct equivalent to the Arista AOC-Q-S-40G-50M, this cable delivers exceptional performance for breakout applications requiring individual SFP+ port connectivity. Technical Excellence: Built with premium OM3 50/125 multimode fiber comprising 8 strands, this cable supports 40GB transmission speeds while maintaining signal integrity across its full 50-meter length. The active optical design incorporates integrated signal conditioning, eliminating the distance limitations associated with passive copper alternatives. Compliance certifications include IEEE 802.3ba qualification, RoHS/ELV standards, Class 1 Laser safety, and UL/FDA ratings per 21CFR 1040.10. Superior Construction: The LSZH (Low Smoke Zero Halogen) rated plastic jacketing with riser (OFNR) classification ensures enhanced fire safety in plenum-rated installations. This construction method minimizes toxic smoke and corrosive gases during combustion, making it essential for critical infrastructure and commercial installations where safety codes mandate LSZH compliance. Application Versatility: Ideal for data center backbones, high-speed server interconnects, storage area networks (SANs), and campus network backbone upgrades. The breakout configuration allows a single QSFP+ port to deliver four independent 10GB channels via SFP+ connections, maximizing port density and simplifying infrastructure management. Reliability & Support: Manufactured to stringent international standards with origins in Vietnam and China, this cable undergoes rigorous quality assurance testing. The 90-day limited warranty provides confidence in your investment, while free standard shipping on orders over $99 adds value. Ships from strategically located warehouses in Danville, CA and Beaufort, SC for expedited delivery. Operating in temperature ranges from 0-70°C, this cable maintains consistent performance across diverse environmental conditions. Custom brand programming is available for OEM requirements, and the cable's compatibility with Arista's ecosystem ensures effortless integration into existing network deployments.
